WHAT IS RODIN COIL? It is a special coil that generates frequency waves using a Pulsed Electro Magnetic Field. It is based on a magnetic field theorem, which is based on Vortex mathematics and discovered by Marko Rodin. Activate your Chakra Flow. Harmonize the Energy Frequency of your Food and Water. Change the Energy Field of your room and rooms. Make your Mind and Body feel good & healing yourself. For example, Schumann frequency 7.83 is called the pulse of the world, you can benefit from Solfeggio Frequencies 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, 963 Hz and you can reach different frequencies that will be good for you on the internet. Take advantage of the frequencies of natural stones. WHAT ARE OUTPUT CONNECTION TYPES? It has 3.5mm female aux jack as standard, but it can be customized to work with bnc or different connectors for your different special devices, please consult about it. ARE COILS MONO OR STERIO? Coils are stereo and can play different frequency on both channels, different fields are formed in two directions, just like in your wired headphones. Smartphones can be connected with special wave generators, pc or mp3 players directly with an Aux cable, but your magnetic field generator is dependent on its power. For large magnetic fields, you can use powerful amplifiers or internal powerful frequency wave generators. For example, you may need a booster amp for the magnetic field magnet ball test. The magnetic field effect decreases as you move away from the coils, but theoretically, magnetic field waves can travel very far. (Just as radio broadcasts reach your radio). The stronger the power supplied to the coil and the stronger your coil structure, the wider the area of influence you will achieve. The coils have a standard 3.5mm aux input and can be used with an Iphone or Android device or Pc, mp3 player etc. It can be used directly with the aux cable by playing a frequency generator application or recording using. Taking advantage of much stronger magnetic field or moving magnet etc. For this you need to use a frequency booster amp. If you don’t have a Frequency booster amp, you can find a powerful Frequency booster for Rodin coil of my own manufacture in my shop. Since the bobbins are handmade and produced based on order, color etc. May show cosmetic differences. The body is produced using bioplastic, quartz, natural stones and copper. It can be personalized according to your wishes, please feel free to ask questions. Message me what you want from the color options Red, White, Black.
